-------------------------------------------------------------------------------
97/03/10 1365 Online monitor, PBG Occupancy TDC, ch29 and ch31 are noisy.
(see log book III, pg. 80)
97/03/11 ---- Super-Ring four discriminator, ch13 is shorted with ch14, ch15
is shorted with ch16. So the TDC occupancy for those two
channels are twice as others.
97/03/11 1369 At the end of run, change SR4 discriminator with a good one.
Check threshold and online PBG occupancy TDC is OK.
-------- ---- It was found we have some problems with the neutral trigger.
Some signals were lost in SR4.
97/04/25 2116 At the beginning of the run. It was found that the output
signal width of SR4 discriminator was not set correctly. It was
set as 40 ns instead of 75 ns (dated back to 97/03/11, run
1371). Increase that to 75 ns as other Super-Ring.
97/05/27 Neutral trigger CAMAC special high power supply down.
97/05/28 Put neutral trigger discriminators to two regular high power
supplies and reconfigured the neutral trigger discriminator's
setup. Now everything is working fine.
